Working with the limitations of APM/SWG perflow.custom

Hi,

 

I am after advise for the best way to work with the single perflow.custom variable when i need to set multiple flags/data to later use in vpe decisions boxes. my two initial thoughts where to either use arrays or to work the variable as binary and set bits like flags. But both of these seem clunky to me and vpe code would look very messy and confusing.

 

So does any one have a good approach to this problem?

 

cheers
